S ay: The episode will ask us to either fill in missing numbers on a
number line or hang numbered tags on a number line. Pay attention
to the intervals on the number line. What are we counting by?
Each tick mark represents 5.
Depending on the episode’s problem, ask:
How can we determine how to fill in the missing numbers?or
How can we determine where to place the tags?
We can skip count by 5 to figure out the numbers on the rest of the
number line.

on her board, she will cover it with a token. The first person to
cover three in a row wins.
